a)x+3=-5/-3=> x=-8

b)-x+4=1/-4=> -x=-3/* -1 => x=3

c)-2x+16=10/-16 => -2x=-6/: -2 => x=3

d) -3x-4=-25/+4 => -3x=-21/:-1 => x=7

e)3x+4=-8 /-4=> 3x = -12/:3 => x= -4

f)4x+3 = 2x-8 => 4x-2x = -8-3 => 2x = -11/: 2=> x= 5,5

g) -8x+ 7 = -4-4 => -8x = -8 -7= -15/:-8 => x= 7,5

h) 3x+5=-2x-5 => 3x+2x = -5-5 => 5x=-10/:5 => x=2

i)  4(x+1) = -16 => 4x + 4 = -16/-4 => 4x= -18/: 4 => x=-4,5

j) 16: (2x+2) =-4 => 8x+8=-4/ -8 => 8x=-12/:8 => x=1,5

k) 3x+3-5+6 = -8=> 3x+4 =-8 / -4 => 3x= -12/:3 => x=-4

l) 33x+11=44/-11 => 33x= 33/:33 => x=1

m) 3(x+1)+3=-12 => 3x+3+3 = -12/:6=> 3x= -2/:3 => x= -0.666666

n) x-2 = -2   * -6 => x-2 =12 /+2 => x=14

o) 25: -x= -5/*25 => -x= -125
